Calibrachoa plant named ‘Cal Laver’

ABSTRACT

A new and distinct cultivar of  Calibrachoa  plant named ‘Cal Laver’, characterized by its uniform, outwardly spreading, mounding and trailing plant habit; freely and continuous branching habit; dense and bushy plant growth habit; and very freely flowering habit, numerous lavender-colored flowers with yellow-colored throats.

Botanical classification/cultivar designation: Calibrachoa sp. cultivar Cal Laver.

BACKGROUND OF THE INVENTION

The present Invention relates to a new and distinct cultivar of Calibrachoa plant, botanically known as Calibrachoa sp., and hereinafter referred to by the cultivar name Cal Laver.

The new Calibrachoa is a product of a planned breeding program conducted by the Inventor in Gilroy, Calif. The objective of the breeding program is to create new Calibrachoas with uniform plant growth habit and flowering and flowers that remain open.

The new Calibrachoa originated from a cross-pollination made by the Inventor in September, 2000 of a proprietary Calibrachoa selection identified as 83-1, not patented, as the female, or seed parent, with a proprietary Calibrachoa selection identified as 171-1, not patented, as the male, or pollen parent. The new Calibrachoa was selected as a single flowering plant from the resulting progeny by the Inventor in a controlled environment in April, 2001 in Gilroy, Calif.

Asexual reproduction of the new cultivar by terminal cuttings taken in Gilroy, Calif. since April, 2001 has shown that the unique features of this new Calibrachoa are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the cultivar Cal Laver have not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature and light intensity without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Cal Laver’. These characteristics in combination distinguish ‘Cal Laver’ as a new and distinct cultivar:

1. Uniform, outwardly spreading, mounding and trailing plant habit.

2. Freely and continuous branching habit; dense and bushy plant growth habit.

3. Very freely flowering habit, numerous lavender-colored flowers with yellow-colored throats.

In side-by-side comparisons conducted in Gilroy, Calif., plants of the new Calibrachoa differed from plants of the female parent selection in the following characteristics:

1. Plants of the new Calibrachoa had smaller leaves than plants of the female parent selection.

2. Plants of the new Calibrachoa flowered earlier than plants of the female parent selection.

3. Plants of the new Calibrachoa and the female parent selection differed in flower coloration as plants of the female parent selection had rose-colored flowers.

In side-by-side comparisons conducted in Gilroy, Calif., plants of the new Calibrachoa differed from plants of the male parent selection in the following characteristics:

1. Plants of the new Calibrachoa were more freely basally branching than plants of the male parent selection.

2. Plants of the new Calibrachoa flowered more uniformly than plants of the male parent selection.

3. Plants of the new Calibrachoa and the male parent selection differed in flower coloration as plants of the male parent selection had lavender rose-colored flowers.

Plants of the new Calibrachoa can be compared to plants of the Calibrachoa cultivar Million Bells Sweet Pink, not patented. In side-by-side comparisons conducted in Gilroy, Calif., plants of the new Calibrachoa differed from plants of the cultivar Million Bells Sweet Pink in the following characteristics:

1. Plants of the new Calibrachoa were more upright and had longer internodes than plants of the cultivar Million Bells Sweet Pink.

2. Plants of the new Calibrachoa had lavender-colored flowers whereas plants of the cultivar Million Bells Sweet Pink had red purple-colored flowers.

3. Sepals of plants of the new Calibrachoa were longer and darker green-colored than sepals of plants of the cultivar Million Bells Sweet Pink.

The photograph at the bottom of the sheet comprises a close-up view of typical flowers and leaves of ‘Cal Laver’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations and measurements describe plants grown in Gilroy, Calif., under commercial practice during the summer in a polycarbonate-covered greenhouse with day temperatures about 24 to 34° C., night temperatures about 13 to 18° C., and light levels about 2,000 foot-candles. One rooted cutting was planted per 15.25-cm container. Plants were pinched one time and were grown for about 12 weeks. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 1995 Edition, except where general terms of ordinary dictionary significance are used.
